Set OSMO_FSM_DUP_CHECK_DISABLED for grgsm_scanner and grgsm_livemon

Browse Source 
apt-packaged gr-gsm aborts with SIGABRT (-6) due to duplicate FSM
registration in libosmocore. Setting this env var suppresses the
fatal assertion, allowing grgsm_scanner to run normally.

Applied to both scanner and livemon subprocess spawns.
